CHARLES H. ADAMS, OF FREELAND, MICHIGAN.

- SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 393,876, dated December 4, 1888. Application filed September 1D, 1888. Serial No. 285,046. (No model.)

To all whom it may concern.-

Beit known that I, CHARLEs Il. ADAMS, a citizen of the United States, residing at Freeland, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Seal-Locks for Freight- Car Doors, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in seal-locks for freight-car doors; and the invention consists in the peculiar construction and arrangement of the parts, all as more fully hereinafter described.

In the drawings which accompany this specification, Figure l is an elevation of a freightcar door, showing my improved seal-lock applied thcreto. Fig. 2 is an enlarged elevation of my seal-lock. Fig. 3 is a detached perspective view of the same. Fig. 4 is a vertical central section thereof. Fig. 5 is a perspective view of the seal, and Fig. G is across-section on line fr in Fig. 2.

A is a bed-plate by means of which the device is attached to the rear end of the cardoor7 suitable screw-holes, d, being provided for therein.

B is a spring-latch secured near the upper end of the bed-plate and terminating in a handle, C.

'D is a strap which connes the spring-latch.

E is a locking-tongue secured to the springlatch and adapted to project through the slot F in the bed-plate and a corresponding slot in the door sufIiciently-to prevent the opening of the door by projecting over the jamb of the door when the spring-latch is depressed.

. ing-latch down upon the bed-plate when in-A G is a locking-key adapted to hold the lockserted transversely through the key-seat b, formed in the confining-strap D. This key is preferably carried by means of the chain H' alongside the device.

I is a lead seal provided with the shank d. J and J are corresponding apertures in the Abed-plate and in the locking-latch to receive the shank of the seal. The aperture J is preferably provided with the conical nipple K, which projects from the face of the bed-plate, and the corresponding recess, J', is adapted to receive it on the under side of the spring'- latch.

M is a riveting-head secured at the bottom of the aperture J some dist-ance back of it, to form the recess N to permit rivet-heading the shank of the seal, a suitable bridge, O, leading the seat to the bed-plate, as will be understood from reference to Fig.

V is a sealing-tool provided with the driving-head T and the seal-head R, which carries an appropriate mark, letter, or numeral, and an abutment, P, is formed on the upper end of the tool to engage with the strap D, as shown in Fig. 4.

In practice, the parts being constructed and arranged as described, they are intended to operate as follows: The normal tension of the spring-latch B withdraws the tongue E sufliciently t0 permit of freely opening or closing the door; but if the spring-latch is depressed the tongue E impinges against the Vjamb of the door, and thereby prevents the opening of the same. To seal the car, the seal is inserted with its shank into the aperture J of the locking-latch. vrl`hen the sealing-tool is inserted, as shown in Fig. 4.-, and by grasping the handle C and the handle of the sealing-tool the locking-latch will be depressed and the stud of the seal entered into the aperture J of the bed-plate. By exerting sufficient pressure the riveting-head M will then upset or rivet-head the shank of the seal and impart the mark cf the sealing-head on the seal. By inserting the key into the keyways of the coniining-strap any accidental displacement of the lockinglatch is prevented. Any tampering with the car is prevented without detection, as the opening of the door cannot be effected without breaking the seal, the replacement of Vwhich without the sealing-tool and its distinguishing mark cannot be effected without being plainly noticeable. To adapt the device for use with the ordinary car-seals, which are secured to wires or tins, I provide the end of the key with the slots c, suitable to receive such wires or tins.

The obj ect of providing the apertures J with the nipple and forming the corresponding recess around the aperture J to receive the shank is to prevent the spreading of the shank IOO oi' Ithe seal in :in v other wa)v but the one proprovided with the transverse kevway, a key 23 dueingl the rivet-head, as sueh nipple eutirehv eouues the shank except a small portion otl its end, whieh projeets beyond to t'ornl the rivet-head.

That I eiaini as nrv invention is- 1. In a seal-leek, the eoinbination of the bed-plate seeured to the door, the spring-lateh secured thereto and earr'vinel a loek ine-tongue working through a slot in the bed-plate and door, the eontilting-strap over the lateh provided with the transverse keywav, the ke'v adapted to engage therein7 the apertures iu the bed-plate and iateh to reeeive the shank ot' the seal, and the riveting-diend seeured behind the bed-plate, the parts being' arranged to operate in eonneetion with the lead seal with the Shank, subst ant'iailv as and t'or the purpose described.

2. In a` seal-leek, the eolubiuation of the bed-plate seeured to the door, the spring-hitch seeured thereto and earrying' the locking# tongue workingl through a sloty in the bedplate and door, the strap over the spring-iateh adapted to engage therein and having thel i slots to reeeive the ordinary ear-seals, and ot' the sealingl deviee consisting' of the apertures J and .'I, and the riveting-head M, and the sealing-tool, substantially as described.

I3. In aV seal-lock, the Combination ot' the bed-plate A,the spring-latch lseeured thereto and earl-ying' the tongue E, the eoni'ining-strap I), having transverse ke'vway, the locking-key adapted to engage therein and provided with the apertures e, the apertures J and J',

` the nipple K, the riveting-head M, and the sealing-tool V, having; the driving-head T, the sealing-head R, and the abutment I), the parts being arranged to operate substantially as and For the purpose described.
